You will now find that air purifiers are found in most homes and even some workplaces. People who suffer from allergies and asthma now use purifiers to clean the air so they can breath easy. When you want to buy on, the sheer amount of technology can be confusing.
By reviewing the top air purifier technologies we hope to give you the information so that you can choose the right machine for your need.
Air purifiers work by removing pollutants from the air inside a building. Here are the 5 most popular air purifier technologies:
1.Ultraviolet Germicidal Irradiation (UVGI)-this kills germs contained in the air through UV irradiation. However, they are not considered to be highly efficient as most harmful bacteria and molds require a lot of UV light to be destroyed.
2. High Efficiency Particulate Air (HEPA) filters trap particulate matter efficiently (99% of all 0.3 micrometer particles can be trapped as well as a significant portion of smaller particles). The efficiency of HEPA filters is maximized when air is unable to circulate around the filter. This means airtight rooms that ventilate through specified ducts, which is not the case of most homes.
3. The technology of activated carbon is based on the fact that carbon activated will adsorb pollutants on a molecular level. The efficiency of activated carbon is a bone of contention as once the carbon reaches equilibrium with the surrounding air then no more pollutants will be removed. If the amount of chemicals is high on the filter then some of these might be released back into the air.
4. Ionic air purifiers do not use a polymer or paper like the technology used in HEPA units. Ionizing purifiers charge the particles so that they are attracted to the plates that are the opposite charge. Ionizer purifiers make a lot less noise than most HEPA based machines. Ionic purifiers are able to remove the very smallest of particles but are not so helpful with doors or germs.
5. PCO (Photo-catalytic Oxidation) might be a the major air purification technology in the future due to its promised efficiency for very low energy consumption. Currently PCO can not be used in homes as it has problems removing gaseous pollutants created during the reaction process.
Once you have read our reviews of the top 5 technologies we hope that you will find it easy to choose which technology is right for you.
